It makes me think of the story of the little boy who was throwing the starfish from the beach back into the ocean. An older man came along and said, "What are you doing? You're wasting your time! You can't help all of these starfish. You can't make a difference." The little boy said as he threw another starfish back into the ocean, "I made a difference to that one."
You see, we can't help everyone. The need is too great. But we can help one. So today, "Do what you can, with what you have, where you are." We may not can make a difference to everyone, but we can make a difference to just one. You're where you are for a reason. Allow God to guide you and do His Will to help someone else today.
And let us not grow weary of doing good, for in due season we will reap, if we do not give up. Galatians 6:9
